STITCH-TRANSFERRING DEVICE FOR KNITTING-MACHINES.

Application filed April 30, 1915.

To all whom it may concern Be it known that 1, Louis N. D. lV IL- LIAMs, a citizen of the United States, res1ding in Ogontz, Pennsylvania, have invented certain improvements in Stitch-Transferring Devices for Knitting-Machines, of

I which the following is a specification.

The object of my invention is to provide simple and efficient means for first remov-.

'Iattain in the manner hereinafter set forth,

7 reference being had to the accompanying drawings, in which- Figure 1 is a vertical sectional view 0 suhicient of the needle cylinder of a circular knitting machine to illustrate the application of one form of my invention thereto;

Fig. 2 is a view similar to Fig. l but showing another adaptation of my invention, and Fig. 3 is a bottom view of the web holde operating cam' ring;

In the drawings, 1 represents the cylinder of a circular knitting machine, 2 the needles around one-half of the cylinder, 2 theneedles'around the other half of the same, 3,3. the web holders, 4 the ring in which said web holders are slidably mounted, and 5 the cam ring for imparting to-and-fro reciprocation to said web holders, all of these parts being constructed and operating in the usual manner. The cam ring 5 should, however, be provided with means, such for instance as the switch cam 5, Fig. 3, for retaining all of the web holders in retracted position when desired. I

Mounted inside of the upper portion of the cylinder shown in Fig. 1 is a ring comprising two semi-circular halves 66 having hinge members 77 with pintle 8, in line with the tops of a series of upwardly projecting stitch receiving points 9 on the ring member 6, the tops of these points normally occupying a position below the stitch retaining portion of the web holders. A supporting cylinder 10, however, provides for lifting the ring segments 66 when desired.

Supposing that the knitting operation has been completed ,a dn the ne edles'.2 -2 and it'is desired to double upon the semi-circular Specification of Letters Patent.

set of points 9 stitches from the needles 2 and those from the needles 2*, the ring segments 6(3 are lifted until the points 9 have received upon their upper ends the stitches last formed upon the needles 2 or the stitches of a previously formed course. The needles 2, before or after this operation, having been projected to such a position that the latches are clear of the stitches, said needles 2 are then retracted so as to cast the stitches therefrom and the web holders 3 having previously been retracted, the section 6 of the ring and its points 9 is then swung to the reverse position shown by-dotted lines in Fig. 1, so that each of the points regis Instead of using ring segments on the inside of the needle cylinder they may be disposed upon the outside of the needles, as shown in Fig. 2, and in such case, when the web holders have been retracted, the points 9 engaged with the stitches upon the needles 2 and said stitches cast or otherwise freed from said needles the points with the stitches upon them may be moved to the position shown by dotted lines, and may either receive the stitches from theneedles 2 or the points may transfer the stitches carried by them onto said needles 2 to be knitted into a succeeding web. I I

In Figs. 1 and 2 of the drawings I have only shown a single needle at each side of the needle cylinder and a single point 9 on the ring segment 6 as the showing of all of the needles and points would lead to con,- fusion and is not necessary for a proper understanding of my invention.

While it is always preferable to hinge the semi-circular quill carrier to a fixed member, such fixed hinges are not absolutely that shown by dotted lines, and although my invention has been designed particularly with reference to doubling stitches produced upon the needles of one-halt ot' a circular knitting machine with those produced upon the needles at the opposite half of the machine it. can. with advantage. he used in connection with that type of knitting machine in which two straight parallel rows of needles are employed arranged back toback and with just suliicient space between them or the passage of theknitted web.

am aware of the patent of \Yalter D. But/3, nun'ibered 1.068.853 and dated July 25 1.913. in which two semi-cirtailar series of stitch receiving points were hinged togethe' in line with the ends of the points, the circular series of quills first receiving the stitches 'lrom the needles of a circular knitting machine and one-halt o't the points being then ttu'ned'over so as to be directed toward the other halt (it the points so that the stitches from one set of points could be transferred to the other set and doubled thereon with the stitches already upon them. but in carrying out my invention I only use one set ot points which co-act directly first with one set. ot needles and then with the opposite set the doubling operation being etl ected simultaneously with transfer of the second set of stitches.

I claim:

1. Its a means of doubling stitches formed at one side of a knitting machine with stitches Formed at the opposite side of the same. a series ot' stitch receiving points mounted so as to register with and receive stitches at one side of the machine. said points being susceptible. of assuming a reverse. position so as to register with stitches at the opposite side ot' the machine. and at one and the same operation etlect both trans fer and doubling of stitches when in the latter position.

2. As a means of doubling stitches formed at one side of a circular knitting machine with stitches tormed at. the opposite side of said machine. a segmeutally disposed series of stitch receiving points mounted so as to register with and receive a semi-circular set of stitches at one side of the machine, said points being susceptible of assuming a. reverse position so as to register with a semicircular set of stitches at the opposite side of the machine. and at one and the same operation effect both transfer and doubling of stitches when in the latter position.

3. As a means of doubling stitches formed at one side of a knitting machine with stitches formed at the opposite side of the same, a series 01 stitch r ceiving points. a'

carrier therefor. and a fixed member Le which said carrier is hinged at a point in line with the tops of the points. whereby said points may be aused to register with and receive stitches at one side of the machine or can be reversed in position and caused to re -ister with stitches at the 0pposite side of the machine, and at one and the same operation etlect both transfer and doubling of stitches when in the latter position.

i. As a means of doubling stitches formed at one side of a knitting machine With stitches formed at the. opposite side of the same. a series of stitch receiving points mounted so as to register with stitches at one side of the machine and susceptible of assuming a reverse position so as to register with stitches at the opposite side of the machine. and at one and the same operation etlect both transfer and doubling of stitches when in the latter position, and means for moving said points to cause them to engage with the initial stitches before reversal of position. i

The combination of the needles of a knitting machine. the web holders, means for retaining the latter in the retracted position, and a series of stitch receiving points mounted so as to register with and receive stitches at one side of the machine and susceptible of assuming a reverse position so as to register with stitches at the opposite side of the machine, and at one and the same operation effect both transfer and doubling of stitches when in the latter position. 1

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
